In this activity, you will be given a scenario about a person who drinks lots of water and exercises but does not urinate as frequently. You will be required to explain the urinary system processes that account for this. (100 min)

Step 2: Analyze

Study the hypothetical case scenario below

Mildred's New year resolves to improve her health by adopting healthy lifestyle changes. The first goal on her list is to drink 3 liters of water daily and exercise 3 times a week at the gym. Although Mildred is excited that she can keep up with her New Year resolution, she is worried as the volume of her urine changes on days she drinks lots of water and exercises vigorously. She has booked an appointment with her family doctor to discuss her concerns.

Step 3: Respond

Prepare a 200 - 250 word assessment describing the process involved in urine formation. Consider the following points:

1. Highlight the difference in Mildred's water requirement when she is exercising vs when she is not exercising. 
2. With these differences in mind, explain the following in both situations:

• Describe how and where water is reabsorbed in the kidney.
• Explain the role of Antidiuretic hormones, Aldosterone and Renin in the reabsorption of water.
